You would have seen an increasing amount of “junk mail” showing up in your e-mail box. The so-called harmless activities of a small number of
people are increasingly becoming a serious problem for the Internet.
Spam is the flooding of the Internet with many copies of the same message, in an attempt to force the message on people who would not
otherwise choose to receive it.
Spam is basically electronic junk mail or junk newsgroup postings. It is sometimes confused with any unsolicited e-mail. But an old friend may
also find your e-mail address on the Net and send you a message but this could hardly be called spam, even though it is unsolicited. Real spam is
generally e-mail advertising for some product sent to a mailing list or newsgroup.

Text of page 84
In addition to wasting people’s time with unwanted e-mail, spam also eats up a lot of network bandwidth. There are many organisations and
individuals who have taken it upon themselves to fight spam with a variety of techniques. The problem is that because the Internet is public, there
is very little that can be done to prevent spam, just as it is impossible to prevent junk mail.
One of the most recent examples of large-scale spamming was the hoax Ericsson e-mail about a free give away, something most people just
cannot resist. The letter begins with a claim that since Nokia is giving away telephones, Ericsson will respond by giving away brand new WAP
phone. But the recipient must forward the letter to a minimum of 20 people to receive the phone. The letter is signed by Anna Swelund,
Executive Promotion Manager for Ericsson Marketing. It was later discovered that there was no such person at Ericsson.
